Patent GB-627573-A (GB)
Title: Improved process for the alkylation or polymerisation of hydrocarbons
IPC: C07C2/86
Filed: 1949-07-05
Abstract: In a plate column, the overflow from the bottom plate is conveyed to a decanter for separating reaction products, and vapours rising from the base byepass through the bottom plate and bubble into the next plate.  In a modification, the capacity of the bottom plate is enlarged and this plate itself forms the decanter.ALSO:<PICT:0627573/IV (b)/1> Polymerization or alkylation of hydrocarbons with an aluminium halide catalyst is effected continuously in a plate column to the top of which at least one of the reactants is fed, the height being calculated so that reaction is complete when the products reach the base, and which is heated by a counter-current of the vapours of a solvent used to dissolve the complex of aluminium halide and reaction product.  The solvent may be an excess of one reactant, and the complex may be drawn off when it reaches the lowest plate.  Dibenzyl and butyl chloride in the form of a complex with aluminium chloride are fed from tanks 1, 2 respectively to the top of a plate column 3 heated to give a base temperature of 95 DEG  C. and a top of 60 DEG  C. by means of reflux 5 from condenser 6 and cooler 7.  Hydrochloric acid is absorbed in a coil 9.  The complex produced, diluted in excess of butyl chloride, is removed at the base, decanted at 12, the lower layer returned to the top of the column by pump 13, and the upper layer hydrolyzed at 14 and decanted at 15 after washing.  Polymerization may be effected in the upper part of a high plate column, and alkyl chloride supplied to an intermediate plate where polymerization is complete, if necessary with fresh aluminium halide.  When one reactant is gaseous, as in alkylation with a gaseous chloride, this may be supplied to the base of the column. p  In a modified column (Fig. 2, not shown), wherein the reflux 5 is returned in part to the top plates and in part to the base 4, liquid from the bottom plate is cooled and passed to the decanter while vapours from base 4 pass direct to the penultimate plate and thence rise from plate to plate.  A further modification (Fig. 3, not shown), utilises the bottom plate as the decanter by increasing its capacity so that decantation is effected in the heated column.

Title: Processes for preparing gas mixtures containing hydrogen and carbon monoxide
Inventor: HARR LEONARD WILLIAM TER
IPC: C10K1/04
Filed: 1964-05-14
Abstract: In a process for making a combustible gas by partial combustion of a hydrocarbon oil, optionally with steam, at elevated pressure, the sootcontaining make gas is washed with water or steam and the aqueous suspension of soot so formed is contacted with a hydrocarbon oil to form soot/oil aggregates which are separated from the water and pulverized and mixed with further hydrocarbon oil to form a fuel which may be recycled as feedstock to the partial combustion process. The water content of this fuel may amount to less than 4% by weight. The same oil may be used as feedstock, for forming the aggregates, and for the final step, e.g. a residual fuel oil, or a lighter oil, e.g. gas oil, may be used to form the aggregates.  Pulverizing and mixing may take place in a colloid mill, and an unspecified solid catalyst may be added at this stage.  The final fuel is compressed and heated before delivery to the reactor.  A flow diagram (not shown) is provided.ALSO:In a process for making a combustible gas by partial combustion of a hydrocarbon oil, optionally with steam, at elevated pressure, the soot-containing make gas is washed with water or steam and the aqueous suspension of soot so formed is contacted with a hydrocarbon oil to form soot/oil aggregates which are separated from the water and pulverized and mixed with further hydrocarbon oil to form a fuel which may be recycled as feedstock to the partial combustion process.

Filed: 1925-08-12
Abstract: 255,655. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Aug. 12, 1925. Gases, separating mixtures of.-In separating organic gases and vapours from moist gases by. means of a solid adsorbent, the adsorbent is arranged or selected so that the moisture and the organic product are adsorbed in turn at different stages. For example, a hydrophile adsorbent, such as silica gel, alumina gel, or natural or artificial zeolite, may be arranged in a series of vessels through which the moist gases are passed, the arrangement being such that, when the system is saturated, the adsorbent in the first vessel is charged substantially with water and that in the last vessel with the organic product. Alternatively, a combination of hydrophile adsorbents having pores of different width may be used, the first vessel containing the adsorbent having wider pores; it is stated that the width of the pores depends, to some extent, on the purity of the adsorbent and can be varied by varying the conditions of drying. According to a further modification the moist gases are passed in turn through a hydrophile adsorbent and a hydrophobe adsorbent, such as active charcoal. In reactivating, the adsorbent containing the organic pro. duct is treated, optionally in vacuo, with steam and that containing water with hot fine or waste gases.

Abstract: 531,118. Treating ores. LORING. P. F. July 12, 1939, Nos. 20289 and 20290. Convention dates, July 12, 1938, and Sept. 14, 1938. [Class 82 (i)] Complex ores, or concentrates, particularly gold ores containing arsenic and antimony, are ground and mixed with tar or pitch and the mixture is coked in a non-oxidizing atmosphere, with the elimination of some sulphur. The product is broken up and heated in an oxidizing atmosphere to drive off volatile constituents such as antimony and arsenic oxides, and the residue is treated in known manner for the extraction of the gold and other metals. The apparatus in which the oxidation is effected may comprise a horizontal tube containing longitudinal grids on the uppermost of which the coked material is supported, the tube being heated externally except at its ends and air being drawn through it ; as the heating proceeds, the material breaks down to a fine ash and falls to the bottom of the tube from which it is collected.
Patent GB-829072-A (GB)
Title: Production of high octane motor gasoline
IPC: C10G69/04
Filed: 1958-06-25
Abstract: High octane gasoline is produced by catalytically cracking a hydrocarbon oil boiling above the gasoline range with a silica-alumina type catalyst, separating from the products an unsaturated catalytically cracked gasoline having an end B.P. of between about 82 DEG  and about 121 DEG  C., catalytically hydrogenating the cracked gasoline until its bromine number is reduced by between about 25 and about 95%, and blending with the partially hydrogenated gasoline at least 12% by volume based on the gasoline, of one or more saturated alkyl ethers boiling between about 31 DEG  and about 82 DEG  C.  In addition to the catalytically cracked gasoline, the cracked products may be separated into gaseous olefin and naphtha fractions, the olefins being used to make the ethers by reaction with alcohols, e.g. methanol or isopropanol, while the naphtha fraction may be catalytically reformed, e.g. by means of a platinum-alumina-halogen catalyst in the presence of re-cycled hydrogen, and then combined with the blend of hydrogenated catalytically-cracked gasoline and the ether.  Preferably the cracked naphtha is reformed to an octane number less than that of the blend. Specified ethers are isopropyl tertiary butyl, di-isopropyl, methyl isopropyl, ethyl isopropyl, methyl tertiary butyl, ethyl tertiary butyl and methyl tertiary amyl ethers, and also 4,4 - dimethyl 1,3 - dioxane. Hydrogenation of the cracked gasoline is effected using catalysts exemplified by alumina or silica-alumina as supports for oxides or sulphides of one or more of copper, cobalt, nickel, chromium, molybdenum and tungsten.
